newly-exec()ed user-land process for the new dl*-capable crt0:
a0 stack pointer (points to onstack argc)
a1 rtld cleanup (filled in by dynamic loader)
a2 rtld object (filled in by dynamic loader)
a3 ps_strings
From Jason Thorpe (thorpej@nas.nasa.gov).
Expects additional register-passed arguments from the kernel on
exec(). If no such args ($a0 is zero), fall back to the old hack of
adjusting the current $sp with a hard-coded frame offset for __start's
local frame(!).
Suggested by Jason Thorpe (thorpej@nas.nasa.gov), debugged and
stackframe offsets updated by Jonathan Stone.
ktlbmiss on the kernel stack. It was showing the temporary SP, not the
original SP.
Add a display of the first few wired entries of the TLB so when the ktblmiss
occurs, the TLB entries mapping the kernel stack can be verified.
- Add optional "geomspec" argument as third argument when configuring
a vnode disk. Format is: secsize/secpertrack/trackpercyl/ncylinders,
e.g. 512/18/2/80.
- Add optional "-t typename" argument, mutually exclusive with "geomspec",
that will look up "typename" in /etc/disktab and use the geometry
specified in the entry.
- Update verbose output accordingly.
greater flexibility in its use. Additionally, add support for "geometry
emulation". This allows the "geometry" of the "disk" to be specified
at config time, providing near-perfect emulation of disklabel-less floppies,
CD-ROMs, etc., including non-512-byte sectors. If a geometry is not
specified at config time, a default based on 1M cylinders will be used.
directory at the same level as 'foo' called 'bar'. (e.g, a definition
of usr/obj exists, and a def for usr/bin, but none for usr/obj/bin. don't
warn about usr/obj/bin because of the usr/bin entry).
